package.json scripts

},

editor.css and/or style.css

@import "tailwindcss";

.wp-block-sample-block-1 {
	background: yellow;
}

in edit.js I'm importing css file

import './editor.css';

and I have mapped classes like it's described in docs

const PADDING_CLASSES = {
	default: {
		0: 'py-0', 1: 'py-1', 2: 'py-2', 8: 'py-8', 10: 'py-10'
	},
	sm: {
		0: 'sm:py-0', 1: 'sm:py-1', 2: 'sm:py-2', 8: 'sm:py-8', 10: 'sm:py-10'
	},
	md: {
		0: 'md:py-0', 1: 'md:py-1', 2: 'md:py-2', 8: 'md:py-8', 10: 'md:py-10'
	},
	lg: {
		0: 'lg:py-0', 1: 'lg:py-1', 2: 'lg:py-2', 8: 'lg:py-8', 10: 'lg:py-10'
	},
	xl: {
		0: 'xl:py-0', 1: 'xl:py-1', 2: 'xl:py-2', 8: 'xl:py-8', 10: 'xl:py-10'
	},
	'2xl': {
		0: '2xl:py-0', 1: '2xl:py-1', 2: '2xl:py-2', 8: '2xl:py-8', 10: '2xl:py-10'
	}
};

in render.php file I have sample div with class py-4

<section <?php echo get_block_wrapper_attributes(); ?>>
	<div class="py-4">
	</div>
</section>

After running build command I can see files in the /build directory. CSS file content

As you can see the classes are not generated. What am i missing?

Hey there! From the output it seems like Tailwind CSS did not run at all on your config. There needs to be a build step where you call the Tailwind compiler via any of the integrations listed on our website: https://tailwindcss.com/docs/installation/using-vite This will be based specifically on your project setup so something that works with Wordpress React Blocks but I have not used that before so moving it to a discussion in case someone else has any idea!

I think I've got it solved. It's a bit tricky but it works.

1. Installed tailwindcss/cli package
2. Create 2 additional scripts in my package.json

"tailwind:build-editor": "find ./src -name 'editor.css' | while read file; do output=./build/${file#./src/}; output=${output%editor.css}index.css; mkdir -p \"$(dirname \"$output\")\"; npx tailwindcss -i \"$file\" -o \"$output\" --minify; done",
"tailwind:build": "find ./src -name 'style.css' | while read file; do output=./build/${file#./src/}; output=${output%style.css}style-index.css; mkdir -p \"$(dirname \"$output\")\"; npx tailwindcss -i \"$file\" -o \"$output\" --minify; done",

Script will look for files editor.css in subdirectories (in case if there will be more than one block) and process the file to proper output. I'm doing the same for the style.css file

3. Update buld and start scripts

"build": "wp-scripts build --webpack-copy-php && npm run tailwind:build && npm run tailwind:build-editor",

I didn't update watch scripts because I don't need them right now.
